Where to find Lithium

Answer first

Best farm: volcanic caves under Cicada Wreck (Empty Hold) ~400 m east of the Lifepod after Heat Tolerance — purple/yellow blocky deposits, Sonic Resonator required. Early alternative without heat: Great Jaw ~300 m south (pink-threaded chamber; do not touch threads).

Field notes

MaterialsLithium
ToolsSonic Resonator, Heat Tolerance (volcanic)
Depth / zoneGreat Jaw / volcanic caves

Steps

  1. Clear the first Angel Comb for Heat Tolerance before long volcanic runs.
  2. Swim east into red-tinted Hydrothermal Vents water; find Cicada Empty Hold tangled in rocky roots.
  3. Enter crevices under the wreck — walls hold many Lithium nodes; mine with Sonic Resonator.
  4. Early / no-heat option: ~300 m south past Cicada Canteen into the Great Jaw; harvest Lithium inside the pink-string structure carefully.
  5. ConsolePulse also notes a southeast seafloor hole route with Lithium then Gold deeper — useful alternate loop.
